Tooth enamel - Wikipedia
Tooth enamel is one of the four major tissues that make up the tooth in humans and many animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp.
Enamel: Anatomy, structure and function - Kenhub
2023年10月30日 · The enamel is the hardest substance present in the human body composed mainly of calcium hydroxyapatite and partly of organic materials (proteins). The main structural units of the enamel are the interlocking columns called enamel rods (enamel prisms). The arrangement of these rods is crucial for the enamel's hardness.
